To all whom it may concern."

' Be it known that 1, Warm e. am.

citizen of the United States, residing at Meohanic Falls, in the county of Androscoggin and State of Maine, have invented certain new and useful 1m 'ro'vements in Perforat ing-Machines, of w ich the following is a specification. y

My invention relates to perforating, ma-

chines, and more particularly, to machines of the rotary type designed especially for forming series of uniform perforations in sheets or webs of paper or similar material.

- One object of my invention is to provide a machine of this character by means of which a comparatively wide web -of paper can be perforated in such manner that it may afterward be cut into strips of the required width, having a series of perforations along each edge, such strips being designedfor use in certain well known apparatus having sprocket wheels which engage the perforations.

Another object of the invention is to .provide improved means for supporting the die plates. j A further object of'the invention is to provide an improved construction of rotary punch. A still further object of'the inventionis to provide improved means for adjusting the rotary punch to and from the die plates.

With the above and other objects in view, my invention consists in the construction and arrangement of arts hereinafter described, and illustrated in the accompanying drawings, in which t Figure 1 is a front elevation of the perforatingmachine, com lete; Fig. 2 is a transverse section thereo on an enlarged scale, taken substantially on the line 22 *of Fig.

1; Fig. 3 is a fragmentary longitudinal sec tion, on an enlarged scale, through the die plates and the supporting rin s therefor;

Fig. 4 is a transverse section on ne 44 of Fig. 3; Fig. 5 is an end elevation of one of the clamping rings hereinafter described; Fig. 6 is an end elevation of the machine as shown in Fig. 1'; Fig. 7 is a front elevation of a portion of the sup ortin frame; Fig. 8 is an enlarged sectiona detai on the line 88 of Fig. 7;. Fig. 9 is a side. elevation of one of the punch carrying disks; Fig. 10 is a transverse section of one ofsaid disks; Fig. 11 is 1 10 serving to shown may be rectangular in shape. Sulpported in the frame are a air of paral shafts 2, 3. The shaft 2 1s journaled in bearings 4, and the shaft 3 is journaled'in end bearings 5, and also In a middle bearing or journal box 12, supported by means of a screw threaded standard 11, passing through the lower chord of the frame, and adjustably.

secured in lace by means of locknuts 13.

As cleary shown in Fig. 8, each of the journal boxes 5 is slightly adjustable in the frame and is held in position by means of a yolge 6. plunger 7, behind which is a coil sprlng 8, is arranged in a pocket in the frame.

1, and is ada ted to bear against the u per side of each ofsaid journal boxes 5. A ong stud screw 9, is set into the frame 1 at each end of the machinev and is adapted to bear at its end u on the lower side of each journal box 5. y means of these screws it is evident that the journal boxes may be slightly raised and lowered, the, spring 8 serving to maintain the lparts in contact and a lock nut old thescrew 9 in its adjusted position.

Pinio ns 14 and 15 are-secured to one end of the shafts 2 and 3, respectively and cause them to rotate together. Power may be supplied to the machine througll the extended end of one of the shafts, as 3, by means of a driving'pulley (not shown).

Mounted on the shaft 2 is a series of spacin I adapted to receive the edges of the annular plates 19, and thus support the same, .B means of this construction, the die plates iiich are preferably of steel, may be madef die w comparatively thin and light, and hence may be readlly manufactured and renewed at slight expense.

fora'tions 20 which may be spaced any de 1105 At one end of the shaft 2, adjacent the sired distance apart.

t by means of av The die plates 19 are providedwith a double row of openings-or, pe r i pinion 14, is mounted a clamping ring 23 and adjacent thereto, asupporting ring, 22 having a groove similar to 21 formed in its edge, to receive the corresponding edge of the end die plate. The spacing rings 16 and the supporting and clam ing rings 22 and 23 are provided with j o enings 17 and 24, respectively, for the ischarge of the punchmgs which would otherwise accumulate within the same.

At the other end of the shaft 2 is a supporting ring 25, quite similar in construction to ring 22, and a clam ing ring 26, which is screw-threaded on to t e shaft. It will thus be evident that by screwing up this ring, the various sections of supporting rings and die lates will be clamped rigidly-together and eld in position.

Mounted on the shaft 3 and so spaced as to cooperate with the die plates 19, is a series of punch carriers 27, 28. These are clearly shown in Figs. 2, 9, 10 and 11. By reference to these figures it will be seen that the intermediate punch carriers comprise two diskshaped halves 27 provided on one side with a proecting hub 32 and adapted to be fitted toget er face to face as shown in Fig. 1. The end punch carriers are similar, except that they are formed of one piece only and are rovided with a hub 33 projecting from both aces thereof.

Each punch carrier comprises a diskshaped bodfy portion having formed in one face thereo near the periphery, an annular groove or channel 28. A series of radial openings extend from this channel outwardly to the edge of the disk, and the spacing of these openings corresponds with the spacing of the openings in the annular die plates 19. Within the channels 28 is located an annular thrust plate 29, held in position by means of screws 31.

The punches, which are indicated by the reference character 30, are substantially straight and uniform in cross-section, and are preferably formed of sections of steel wire or rod. These punches are set into the radial openings in the edge of the disk and are of such size that they ma be seated with a driving fit, so as to be he (1 in place against the action of centrifugal force by friction.

The unches abut at their inner ends against the t ust plate 29. It will thus be evident that in case any punch becomes broken, or if, for any other reason, it is desirable to remove one of the unches, the thrust ring 29 is first removed cm the channel, and the particular punch may then be driven inward y through the opening and into the h ii" f h h 8.0 o 't e unc carrying members 27, 28, is preferabfy mounted on bushings 35, clearly shown in Fig. 1 1, which are secured to the shaft by means of set screws 34. It will be seen, therefore, that by loosening any set screw, the corresponding bushing may be shifted longitudinally of the shaft, clear-of the member 27, and such member will then drop down out of operative relation with the correspondin annular die plate.

A brace ro 36 extends from one end of the upper part of the frame to the other and is he (1 in position by means of set screws 40.

Also journaled in the upperpart of the frame in bearings 38, held in position by means of yokes 39, is a shaft or roller 37, over which the paper passes on its way to the perforating mec anism.

It will thus be seen that I have provided a very simple and efficient perforating machine comprising a pair of parallel shafts on which are mounted a series of cooperating die members which may be adjusted relative. to each other, and it is thought that the numerous advantages of my invention will be readily appreciated by those skilled in the art.

What I claim is 1. In a perforating machine, a pair of parallel shafts, a plurality of cooperating, annular die members carried by said shafts, journal boxes in which one of said shafts is mounted at and intermediate its ends, and means for adjusting both said end and intermediate journal boxes toward and away from the other shaft.

2. In a perforating machine, a pair of parallel shafts, journal boxes in which one of said shafts is mounted at and intermediate its ends, means for adjusting said journal boxes relative to the other shaft, and spring pressed plungers carried by the frame of the machine, and bearing against said adjustable end journal boxes.

3. In a perforating machine, a shaft mounted in suitable bearings, a series of l1ollow, cylindrical spacing rings secured on said shaft, and a series of annular die plates supported by said rings between the same.

4. In a perforating machine, a shaft, a pair of spacing rings carried thereby, said rmgs being provided with annular grooves on their adjacent edges, and an annular die plate disposed between said rings and supported at its edges in said grooves.

5. n a perforating machine, a shaft, and a plurality of alternating s acing rings and annular die plates carried t ereby, each of said sipacing) rings comprisingla spider and c linrical ody ortion, suc body portion aving an annu ar groove formed in each edge thereof for sup orting said die plates.

6. In a e orating machine, a shaft, a plurality o alternating perforated, annular die plates and hollow cylindrical spacing rings carried by said shaft, said spacing rings having opgnings therein for the discharge of the punc 'ngs, and clamping rings securing said parts together, and to the shaft.

7. In a perforating machine, a shaft, a

punch carrier mounted onsaid shaft and comprising a disk shaped member having an annular channel formed in one face near the periphery thereof, radial openings extending from said channel to the edge of said member, and punches secured in said openings, said punc es being straight and of uniform section throughout, whereby they may be set into said openings with a driving fit, and, when so desired, driven through said openings into said channel, and thus removed.

- 8. In a perforating machine, a punch car rier comprising a disk-shaped member having an annular channel formed in one face adj acent the periphery thereof, radial openings extending from said channel to' the edge of said member, a removable, annular thrust plate secured in said channel, and straight,- uniform punch ins frictionall held in said openings, and a utting said t rust plate. 9. In a perforating machine, a pair of parallel shafts, a pair of cod crating die memslidably secured to one of said shafts, and on which one of' said die members ismounted, whereby, when said bushing is shifted, said die members are thrown out of cooperative relation. a

10. In a perforating machine, a pair of parallel, shafts, a series of annular die plates mounted on one shaft, a series of cooperating punch carriers mounted on the other shaft, the intermediate die plates and punch carriers being provided with a double row of openings and punches respectively.

In testimony whereof I aflix my signature in presence of two witnesses.
